PROJECT TITLE: Implementation of a heart primitive.
 
  
 
==PROJECT SUMMARY==
 
==PROJECT SUMMARY==
In our world today , we observe that all solid objects are simply combinations of basic ones like cubes,spheres,cones,etc and we frequently have to manipulate objects which have surfaces such as gadgets and devices . With the explosion in ubiquitous technology, Computer-aided design (CAD) software help us create digital content in adverts and movies as well as visualize some solid objects like perfume bottles and shampoo before they are actually manufactured. In this project, we propose that BRL-CAD, which aspires to be the best CAD software, should incorporate a heart, a symbol of love, into its core functionality as one of its basic solid objects in order to increase its customer base and differentiate itself amongst its competitors. Indeed, this heart structure ( also called a heart primitive ) shall be used by those producing cartoons and designing electronic cards, gifts and presents during celebrations such as birthdays, weddings,family reunions, anniversaries and Valentine's day which deeply appeals to many individuals,families and communities.So during the summer, this heart primitive will be included into the raytrace library as a set of routines with corresponding support added to other parts of the source code.
+
We live in a three dimensional world and we frequently have to consider objects which have surfaces - whether these are terrains on planets ,the surface of a gadget, or organs in our internal worlds.In recent times, the need to visualise the surfaces of internal organs such as the heart , liver , brain ,just to name a few,  has escalated due to the explosion in cases of heart disease and cancer. There is an imminent need for the BRLCAD software, which aspires to be the best computer assisted design software, to possess a heart primitive which can assistusers like medical personnel model the heart and plan the effective treatment of cardiac disease.The implementation of a heart primitive also stands as a great opportunity to provide open source C code for the hacker community which can aid in the implementation of other similar geometries which are based on the sextic equations.     
 +
I intend to implement a heart primitive for the BRLCAD software simply by writing a set of routines.These routines will be stored in three (3) files namely hrt.c , hrt_brep.cpp and hrt_mirror.c as is the naming convention of the BRLCAD software primitives.
 +
The hrt.c file will contain routines ( functions ) that execute ray intersection with a heart,a geometric analysis of the heart ,a geometricrepresentation of the heart and constructive solid geometry (CSG) modelling . The hrt_brep.cpp is a piece of source code written in the C++language which executes a  boundary representation of a heart. Finally , hrt_mirror.c will  provide mirror support for the heart primitive against a particular plane .

We include common.h for portability , system headers like stdio.h, math.h and stddef.h, db.h for database interactions, raytrace.h and rtgeom.h . The heart has vertices V,E1,E2,E3,E4 and E5.
 
+
We intend to intersect a ray with a heart by solving the sextic equation of the heart given by the formular
The sextic equation given below by the formula
 
 
F(x,y,z)=0 ------- (1)
 
 
   
 
   
where F(x,y,z) = (x^2 + 9/4*y^2 + z^2 - 1 )^3 - x^2*y^3 - 9/80 * y^3 * z^3
+
            (x^2 + 9/4*y^2 + z^2 - 1 )^3 - x^2*z^3 - 9/200 * y^2 * z^3 = 0.( a^b menas a raised to the power b )
  
defines the surface of the heart and it happens to be symmetric along the x-axis. We need to Solve this equation for x^2 inorder to enable us plot the heart curve in three dimensions.
+
1. We create bounding box for the heart.
To do this, we rewrite the equation into a function of two variables P(y,z) which yields Q(x,y).
+
2.We transform the points on the heart to points on a heart centred at the origin, with a height along the the positive Z axis and a vertex V.
We get x = Q(y,z) = sqrt(P(y,z)).
+
3.We find the point of intersection W of a line with the surface of a heart and the vector normal to the tangent plane at the point of intersection.
The sextic equation above gets sinplified to the formula
+
4.We write routines to interact with the values of the heart in the databse.For example, routine to free the database storage of he heart, change databse formats and export the heart from the databse.
 
+
5. We then write routines to compute the volume, surface area and centroid of the heart.
(a + 9/4*y^2 + z^2 - 1)^3 - a*y^3 - 9/80*y^3*z^3 = 0 ---------- (2)
+
Routines to print the heart , get curve points, plot the heart and tesselate will be written.
 
+
  6. We write routines to return the normal, entry and exit points of a ray .
by a = P(y,z) = x^2.
 
 
 
This gets reduced to a cubic (of power 3) polynomial given below
 
 
 
a^3 + b*a^2 + c*a + d = 0-------------(3)
 
 
 
where
 
 
 
b = P1(y,z) = 27/4 * y^2 + 3 * z^2 - 3.
 
c = P2(y,z) = 405/16 * y^4 - 27/4 * y^2 + z^4 + 9/2 * z^2 * ( y^2 + 1) + 1.
 
d = P3(y,z) = 729/64*y^6+243/16*z^2*y^4+27/4*y^2*z^4-27/4*y^2*z^2-81/4*y^4+9/2*y^2+z^6-z^4 + z^2-1.
 
 
 
The cubic equation in (3) can be solved algebraically using a division method or a decomposition as referenced in the research articles below (See "Links to code and algorithms you intend to use" section in this proposal).
 
The roots of the equation will be Q(x,y) = {a1,a2,a3,a4,a5,a6} where ai = Q(x,y) for i in {1,2,3,4,5,6}.
 
We are now able to plot the heart curve in 3D.
 
 
 
Ray tracing
 
 
 
Now we go over to how I intend to evaluate a ray against the sextic equation in (1).
 
 
 
First of all , I will parametrize the sextic surface equation in (1) by converting it into the form
 
 
 
x = F1(u,v) ----------- (4)
 
 
 
y = F2(u,v) ----------- (5)
 
 
 
z = F3(u,v) ----------- (6)
 
 
 
I intend to compute the normal vector (ray) using the cross product of the partial derivatives of the coordinate functions. That is,
 
 
 
F1u(u,v) = partial(F1(u, v)) / partial(u) ------------- (i)
 
 
 
F1v(u, v) = partial(F1(u, v)) / partial(v) -------------(ii)
 
 
 
F2u(u, v) = partial(F2(u, v)) / partial(u) -------------(iii)
 
 
 
F2v(u, v) = partial(F2(u, v)) / partial(v) -------------(iv)
 
 
 
F3u(u, v) = partial(F3(u, v)) / partial(u) --------------(v)
 
 
 
F3v(u, v) = partial(F3(u, v)) / partial(v) --------------(vi)
 
 
 
where the vectors
 
 
 
tu(u, v) = <F1u(u,v), F2u(u,v) , F3u(u,v)> and tv(u, v) = <F1v(u,v) , F2v(u,v) F3v(u,v)> are tangents to the surface. Thus, we obtain the vector perpendicular to the tangent ( the normal to the surface) which is N(u, v) = p(u, v) / || p(u, v) || where p(u, v) = tu(u,v) X tv(u,v).
 
The normal to the surface N(u,v) is the ray touching the heart from a particular point in 3D.
 
 
 
Rendering
 
 
 
Here, I discuss how I intend to do visualization (geometric representation and analysis). I intend to do this by finding the intersection points between the line (light ray ) and the heart. We simply will write a line-heart test which tells us if a point on the heart surface intersects with the heart. The points of intersection are those that satisfy the line equation and the equation for the surface of the heart at the same coordinates x, y, z.
 
Here , we equate (1) and the equation of the line given below by
 
 
 
X = o + dL --------------- (7)
 
 
 
where d > 0 , X = (x,y,z) is in R^3 and L is the direction of the line.
 
 
 
To search for points that are on the line and on the heart means combining the equations and solving for d. When equations are combined , expanded and rearranged , we get a quadratic equation
 
 
 
a*d^2 + b*d + c = 0 ---------------(8)
 
 
 
which can be solved using the quadratic formula.
 
 
 
d = -b + sqrt(b^2 - 4 * a * c) / 2*a and d = -b - sqrt(b^2 - 4*a*c) / 2*a.
 
  
If the value of b^2 - 4*a*c is less than zero, then it is clear that no solutions exist, that is, the line does not intersect the heart.If it is zero, then exactly one solution exists, that is, the line just touches the heart in one point.If it is greater than zero, two solutions exist, and thus the line touches the heart in two points (the entry and exit point).
+
--hrt_brep.cpp
  
Boolean operations
+
A heart is similar to an epa or seen as an intersection of three elliptic paraboloids (epa).
 +
We include some headers like raytrace.h, rtgeom.h and brep.h to support ray tracing , geometry and boundary representation.
 +
The first is viewed as a canonical paraboloid with a vertex V with coordinates in the negative Z axis opening towards the positive Z axis.Later, a plane is constructed which cuts through the upward facing paraboloid and forms a flat elliptical face.The points where plane intersects with the parabola are noted as E1 and E2.The midpoint of the line E1,E2  called E3 is located on the Z-axis. The midpoints of the line E1 to Z-axis is calculated and a point from this midpoint upwards in the positive Z direction such that the distance from E4 to plane L is |E1 - Z-axis| / 4. Do same to region between Z axis and E2 to get E5.Elliptic paraboloids opening at E4 and E5 opening in the negative Z direction.The epa opening at E4 passes through E1 and E3 while the other epa passes through E2 and E3.       
 +
After, we create a nurbs surface passing through the points V,E1,E2,E3,E4 and E5 and get the nurbs form of the surface.
  
Intersection
+
--hrt_mirror.c
In order to write the intersection of different primitives with the heart primitive , I will solve for the 3D surface R(x,y,z) using the method given above (Equating (1) and the equation of the given primitive).
+
Based on a pointer to the GED database, this file's code mirrors the heart's values about the given trasformation matrix.We follow the following steps:
  
We create bounding box for the heart.
+
1.Perform a mirror down the X axis.
 
+
2.Create the rotation matrix and translation matrices and add them to the mirror matrix.
We transform the points on the heart to points on a heart centered at the origin, with a height along the the positive Z axis and a vertex V.
+
3. Mirror the points V and E1,E2,E3,E4 and E5.
 
 
We find the point of intersection W of a line with the surface of a heart and the vector normal to the tangent plane at the point of intersection.
 
 
 
We write routines to interact with the values of the heart in the database.For example, routine to free the database storage of he heart, change database formats and export the heart from the database.
 
 
 
We then write routines to compute the volume, surface area and centroid of the heart.
 
Routines to print the heart , get curve points, plot the heart and tesselate will be written.
 
 
 
We write routines to return the normal, entry and exit points of a ray .

First of all, I really believe that software can change the world by providing new technologies and that software should be free. I choose BRL-CAD because it is a not-for-profit technology organization which offers me the opportunity to assist the United States Army Research Laboratory with tools which help them simulate and visualize their combat vehicle systems and war events. Working with BRL-CAD also helps me contribute over the long-term and gain status within the hacker community based on my mathematical/Computing background and academic interests.

Although I have not contributed before to opensource ,I see implementing a heart surface primitive as a long-awaited opportunity to provide more primitive options (adding a heart to the raytrace library which is the heart of BRL-CAD) for the BRL-CAD software and a jumpstart to my continued contribution to open source software through BRL-CAD.This project will also help BRL-CAD users to build three-dimensional models related to the heart and love - a virtue we really need in our world today.
